Car vibration at idle

[Muhammad mustafa]

Hello there. I own g70 2023 with 12k miles. I have noticed the car vibrates a bit at idle, specially when I push rpm to 1. Above 2 rpm or when I put the car to D or R its smooth. I can even hear some noise comes from exhaust when it vibrates. There is no fault code or anything, I even checked and cleaned plugs and injections out of curiosity. Tired premium gas and put octane booster still no help. I even put injections a valve cleaner to the tank and still no luck. Could someone help me out please

The car is under warranty; make Genesis figure it out and fix it.

What is it idling at? My 3.3 idles around 600 rpm. I usually shift gears around 2,300 rpm.

Unfortunately no warranty for me. I think it idles around 500 when its a bit warm. The problem is I have taken it to very advanced mechanics and all of them say there is nothing wrong with the car at all. Everytime I come to a stop I put the car to P and push rpm to 1000 and the shaking happens, if I push to 2000 there is no vibration

Why would you want to rev your engine with transmission in P? Seems rather pointless.
